Given the following signalling elements design the optimum receiver?
Given the following signaling elements,
\begin{align}
g_1(t) &= A \quad \text{for} \quad -T/4 < t \leq 0 \\
g_2(t) &= A \quad \text{for} \quad 0 < t \leq T/4 \\
g_3(t) &= A \quad \...

Constrained Least Squares Filter Design
I would like to design a complex FIR filter, $h$, for a known signal that produces a desired output: $d$ = $s*h$ (where $s$ is my signal and $d$ is the desired filter output). Let $S$ be the ...

Degradation of BPSK system using matched filter with a timing error
Given a BPSK system with:
\begin{align*}
s_1(t) &= Au_T(t) \\
s_2(t) &= -Au_T(t) \\
\end{align*}
where $u_T(t)=1$ for $0<t<T$, and zero otherwise. Given $A > 0$, and Gaussian white ...

Optimal receiver for a binary system employing waveform $s=A\cos^{2}(\pi f_c t \pm \alpha)$
I want to design an optimal (minimizing error probability) receiver for system of two waveforms (with $0<\alpha<\frac{\pi}{2}$):
\begin{align}
s_1 &=A\cos^{2}(\pi f_c t + \alpha)\\
s_2 &=...

Minimizing Time Sidelobes with Pulse Compression
I am trying to compute a compression filter function to minimize the error from a a desired pulse compression result.
The usual approach to doing this is to minimize the RMS error of the the ...

Determining signal using Optimal receiver(Matched filter)
I'm given a signal that has been passed through a noisy channel using binary polar signaling with a pulse value of p(t) = 1. The receiver is coherent and the length of each pulse (in samples) is 10 ...

Complex Least Squares Approximation
In the case of frequency domain FIR filter design, the error function given by :
$$E(\omega)=H(e^{j\omega})-D(e^{j\omega}) \tag{1}$$
is a linear function with respect to the unknown filter ...

What is the optimal filter?
I am currently working on a problem on filtering. In fact, let's suppose a signal that is expressed as :
$r(t) = z(t) + x_i(t)$, where $z(t)$ is a smooth function and $x_i(t)$ is white Gaussian noise. ...
